Ingredients
3.5 cups shredded mozzarella cheese, plus 1 cup for toppings -
1.5 cups almond flour
-
1 egg
-
1 teaspoon baking powder
-
1 teaspoon xanthan gum
-
½ teaspoon salt
-
2 tablespoons pizza sauce
-
3 oz prosciutto
-
2 tablespoons diced red onion
-
4 cherry tomatoes, halved
-
2 chives, minced (optional)
Step by Step Instructions
Step by Step Instructions
Melt cheese
Place 3.5 cups of mozzarella in a microwave-safe glass bowl. Microwave for about two minutes until cheese is melted. Stir to combine and make sure all of the cheese is melted. Remove from microwave and let the mixture cool.
Mix dry ingredients
In a large separate bowl, mix together the almond flour, baking powder, xanthan gum, and salt. Set aside.
Mix egg and cheese
Add in your egg to the melted mozzarella cheese. Mix using an electric mixer until combined.
Make dough
Slowly add the almond flour mixture to the cheese mixture. Using an electric mixer or food processor, stir until you have a uniform dough. Don’t be surprised if dough goes flying if you are using the mixer! This can happen, but this is an easy way to combine the mixtures in order to make the best fat head dough. If you don’t have an electric mixer or food processor, I recommend kneading the dough by hand until it comes together. This is a messy and time-consuming process, but the end result is the same – fat head pizza.
Knead pizza dough
Once combined, form a big dough ball. Knead the dough a couple of times on a lightly almond floured surface to ensure the dough is uniform in appearance and all ingredients are fully combined.
Roll out crust
Roll out dough to desired thickness. Remove top parchment layer and place on top of a baking sheet.
Toppings
Sprinkle 1 cup of mozzarella cheese all over the crust. Add prosciutto. Sprinkle diced red onion evenly over the pizza. Add cherry tomatoes all over the pizza dough. Sprinkle chives if using.

This turned out so much better than I expected. The crust had such a great chew to it and actually held together like traditional pizza which I haven't had success with in other keto crusts. The cherry tomatoes roasted beautifully and gave a little burst of sweetness with each bite. Will definitely make it again!
P.S. the wet paper towel trip was soooo helpful…
